Take this network's entry on paradigm.xyz/puzzles/amm to #1 (528.42; ours is qt1 at 524.94, 8th, about +3.5 short). qt1 is Taylor (gtmcknight)'s solved policy (github.com/gtmcknight/amm-sim at 4812a6382311624e1506aca131ca35c378f930d9, research/solved; README first): Gaussian filter + qm tables, about +3.8 over HA on Taylor's replica. The gap is one call: is a step's first own trade the arb or retail. The filter is wrong about 16% of the time; with the true flag the same code scores +6.98 over HA, at the leaders' level. Spend items on that call and on learned corrections to the policy under real observables, measured on Taylor's replica, which knows the true flag.

FILES: each brief names its files (links in the requester's note 1); check every sha256.

GATES: (P) Taylor's gates.py reproduces before any change; (Q) every policy is scored paired against its base reference on Taylor's replica (choose on 64000..65023, report 10000..12047), never choosing on the report seeds; (F) a contract's fees equal its Python reference within 0.01 bps on 50x2,000 replica callbacks.

REPLICA work: plain python3 -I, any machine. CONTRACTS only for a policy >= +0.5 over qt1 on the report seeds: the Linux setup below; deployed <= 24,576 bytes; engine afterSwap peak <= 245,000 and 0 OOG; each strategy alone vs the 30 bps VanillaStrategy, amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs; fresh engine seeds from 9900000 up, never reused; report paired{n,mean_diff,se,worst5} vs qt1. No command over 8 minutes; state under scratch/. Credit Taylor in every header.

The answer

Taylor (gtmcknight) AMM research: final policy and evidence

The strongest delivered contract, R (LEAN tell plus refitted coefficients), gains +3.206713 over qt1 on report seeds 10000–12047: n=2,048, paired SE=0.022401. Its fresh release-engine result is +3.161202, SE=0.035513, n=768. The complete, unchanged Strategy.sol and its two imports are embedded below. The goal did not establish #1, and no leaderboard submission was made. R passes the measured label, fee, size and gas checks, but its 768 engine pairs are 256 short of requester note 7's two × 512 requirement. The larger LEAN sample cannot fill that gap for a different contract. rq-1, rq-2, rq-3, rq-4, rp-1, rp-2, rp-3.

Taylor authored the replica, Gaussian/lattice filters, solved dynamic program and qm tables. This work builds on his pinned solved research and README, commit 4812a6382311624e1506aca131ca35c378f930d9, and IdentityMD's qt1/QMRef, TwoComp/TC-A and COMBO extensions. The delivered improvement comes chiefly from identifying the simulator's floating-point trade path, then retaining a small retail hypothesis when that identification is positive. A coefficient refit contributes a further +0.046805 on the replica and +0.050019 on the engine, paired against unchanged LEAN.

These gas maxima are measurements on the stated samples, not universal bounds. Source identity and statistics were checked again for this write-up; compilation and simulations were not rerun here. The artifact's header still mentions the old blob hash 3ac7cb88…, and getName() still returns TaylorTCALeanTell. Both are preserved so the delivered source has the tested hash. The actual decoded coefficients have the new hash above. rp-1, rp-2, rp-3.

There is no goal trunk repository or merged commit to name: the supplied goal.json has trunk: null, and all 36 batches are research batches. The contract is delivered through the content-addressed item bundles and the source in this report. The execution repository is benedictbrady/amm-challenge at 6b6921f8d463314aa7c96234e1be25a25245f704; that is an upstream pin, not a commit reached by this goal. Notes also reference an external goal's TC-A ancestor in identity-md-launches/goal-3170-beat-network-s-amm-entry at 4eb3e985fd31e3cd17832501b95b6d2491aca73d; it is not this goal's trunk or final R source.

Taylor-derived measurement conventions and gate evidence

“qt1” throughout means the compressed QMRef Python reference and the qt1 Solidity artifact, not Taylor's uncompressed Gaussian+qm gate column. “LEAN” means lb-4's TC-A two-component filter with bounded rounding tell and original QMS1 coefficients. “R” changes only those coefficients to the visit-refit blob. “COMBO” is TwoComp plus weighted-average branch quoting, an earlier base. A gain against COMBO includes neither a gain against LEAN nor an independently measured stack.

Replica figures are total own-pool edge per 10,000-step run, in the simulator's Y units; they are not fee bps or board scores. For each seed, d = candidate_edge − reference_edge; mean is the arithmetic mean of d and SE is sample SD(d)/sqrt(n). “Worst5” means five lowest individual seed differences, ordered by difference then seed. Engine evaluations run each strategy separately against the 30 bps VanillaStrategy, using amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8) with MatchRunner._build_configs configurations. Candidate and qt1 share seed/configuration; they are not matched directly against each other. F compares fees in bps, a separate unit. lb-4, rp-3, cf-2.

The tell's replica evaluations use Taylor's random streams through the engine-order Python port, so callback WAD arithmetic follows the engine. Unmodified replica2 alone does not provide the required rounded callback stream. P and base-port comparisons are therefore separate checks. The release wheel has SHA-256 aedb68280aca34c110968f00148387c95885207913fb2cf19a1ab4c5cfd6887a; workers report checking that pinned wheel and completing the prescribed setup. Source-built diagnostic engine runs from the earlier tell experiments are not mixed into the release-wheel performance sample.

Gate	R evidence	Qualification
P: unchanged Taylor baseline	All three rp and four rq items report the original gates.py values below before changes	Reported worker runs; independently reading source/hash is not a new P run
Q: choose and report	Four 256-seed choose blocks cover 64000–65023; four 512-seed report blocks cover 10000–12047, paired against LEAN and qt1	R selected on choose; prior research had already exposed portions of these common windows, as disclosed below
Q numerical thresholds	R−qt1 +3.206713; worst −1.311917; three negative seeds, none below −2	Exceeds both original +0.5 contract eligibility and later +2.0 tell threshold
T: label parity	350,950 first trades on replica seeds 74200–74249; zero Solidity/reference mismatches in each rp item	All three repeat the same seed stream; do not count this as 1,052,850 unique labels
F: fee parity	50 × 2,000 = 100,000 callbacks; maximum error 4.839644136833687e−7 bps; zero over 0.01 bps	Same test seeds repeated by three builders; F is numerical fidelity, separate from engine gas
G: size and gas	Runtime 22,953 bytes; engine peak 222,787; zero failures across the 792-seed sample	Fits both numeric caps on observed runs
E: fresh paired engine	Three disjoint 256-seed windows, n=768, all with R/LEAN/qt1 arms	Strong measured gain; original two × 512 quota remains incomplete for R

Sources: rp-1, rp-2, rp-3, rq-1, rq-2, rq-3, rq-4. In rp-3, a negative control ran unchanged LEAN against the R reference and failed F at about 4.23 bps, demonstrating that the parity test distinguishes the coefficient sets. rp-2 ran G before Q; rp-3 repaired a test-harness NameError and restarted F. Those procedural departures do not alter the frozen source, but prevent claiming perfect gate-order compliance across every item.

The P reference, corroborated by the pinned Taylor README, is:

Seed	Perfect information	Gaussian/plain	Gaussian/qm	Lattice/qm
10000	448.261189	443.455598	443.522608	443.663520
10001	576.779199	571.463409	571.623551	571.977293
10002	531.886497	525.168028	525.865859	526.411631

Actual qt1/QMRef on those three seeds is approximately 443.101741 / 571.454483 / 525.908441. The full original report-window reference gives qt1−HA +3.705396 (SE 0.038086), TwoComp−qt1 +0.424803 (0.012202) and COMBO−qt1 +0.597391 (0.013388). COMBO with true first-trade flag gives +3.167510 over qt1 (0.022386), or +2.570119 over COMBO (0.020763). That frozen-base intervention is an oracle diagnostic, not a global upper bound on policies. Root 1.

Taylor-derived R selection, paired report and tails

Each rq item used the predeclared rule “R if mean(R−LEAN) > 2 SE on its choose block; otherwise LEAN,” and recorded the choice before its own report block. All four chose R. No policy was selected in this write-up.

Item	Choose seeds	Choose R−LEAN (SE)	Report seeds	Report R−LEAN (SE)	Report R−qt1 (SE)
rq-1	64000–64255	+0.052353 (0.010491)	10000–10511	+0.044785 (0.006685)	+3.172116 (0.045955)

rq-3	64512–64767	+0.059771 (0.010058)	11024–11535	+0.041595 (0.007030)	+3.173857 (0.043250)
rq-4	64768–65023	+0.061482 (0.009678)	11536–12047	+0.059167 (0.007465)	+3.281175 (0.045880)
Pooled	64000–65023, n=1024	+0.052636 (0.004982)	10000–12047, n=2048	+0.046805 (0.003603)	+3.206713 (0.022401)

The pooled report result was recomputed from all 2,048 supplied per-seed rows, with every seed present exactly once. Some rows are rounded to six decimals; six-decimal displayed pooled statistics are appropriate. LEAN−qt1 on the identical rows is +3.159909 (SE 0.022227). R improves the mean while losing to LEAN on 770/2,048 seeds; it is not a pointwise improvement.

The coefficient fit used 64000–64511 visits and selected regularization on 64512–65023 under a different TwoComp+Bayes-tell BASE. Those validation seeds overlap rq-3/rq-4 choose blocks; upstream work also scored the common report window before these confirmations. rq results establish fixed-policy replication and no within-item report tuning, not a newly untouched holdout after the whole research program. The original refit's cap rule changed from one-SE to two-SE after its choose grid; its selected regularization values were weakly separated. These are selection qualifications, not reasons to silently discard the measurements. Fresh engine blocks provide additional evidence on a different seed population. visit-refit, rq-3, rq-4.

Taylor-derived release-engine result and fallback

R's engine seed windows are disjoint. Its score pool excludes the three eight-seed G pilots; its gas accounting includes them. Each item built the same source and paired all three strategies on the same seeds.

Item	E seeds, inclusive	n	R−qt1 (SE)	R−LEAN (SE)	LEAN−qt1 (SE)	R peak gas
rp-1	9993100–9993355	256	+3.129248 (0.059045)	+0.052317 (0.009531)	+3.076931 (0.060051)	221,453

R−qt1 engine worst5: (9995148, −0.387974), (9993174, +0.162958), (9995355, +0.626613), (9995311, +0.785173), (9995268, +0.804769). R−LEAN worst5: (9995204, −0.662688), (9993246, −0.578798), (9994129, −0.512531), (9993244, −0.500469), (9993197, −0.390608). These are retained rather than excluding losing seeds. R safety counts are 2,842,643 + 2,876,593 + 2,859,313 callbacks = 8,578,549, over pilots 9993000–9993007, 9994000–9994007, 9995000–9995007 plus the 768 E seeds.

The fallback is lb-4's original LEAN Strategy.sol, SHA-256 a243bb3570545fb614d8995ced61e811db8e075af68e636add20eaf8fbaeebfb, runtime 22,946 bytes, runtime SHA-256 dab7d69ddb7a172624b37828021941904406326442fb11f750a727e16707d017. Four confirmation items rebuilt it unchanged and reported matching source/runtime identities. This fallback is confirmed on substantially more fresh seeds than R; the direct R−LEAN comparisons, rather than unrelated engine means, support the coefficient upgrade. lb-4, cf-1, cf-2, cf-3, cf-4.

All LEAN E pairs, also rp controls	Above plus the 768 rp seeds	3136	+3.170087 (0.017249)	225,355

All final-LEAN runs above report zero OOG and other callback failures. Including its 32 pilot seeds, the total is 3,168 seeds / 34,419,397 callbacks, not 3,168 independent E pairs. Across the full 3,136 E pairs, worst5 are (9991691, −0.552468), (9995148, −0.515803), (9991141, −0.387310), (9993174, +0.137388), (9991276, +0.345017). cf-3 omitted 9991344–9991535 (192 seeds) because of its stated runtime allowance; they contribute neither zeros nor observations.

Independent LEAN T checks on 74300–74499 cover 1,396,492 first trades with zero mismatches; four F checks cover 400,000 callbacks, maximum fee error 4.820135496253972e−7 bps. These are distinct from lb-4's original T/F seeds and R's repeated T/F stream. The early “tell costs at most 9,800 gas” statement was only lb-4's sample maximum: later probes reached 12,811 for LEAN and 13,055 for R. Whole-callback engine maxima, not isolated tell microbenchmarks, govern the limit. cf-1, cf-2, cf-3, cf-4, rp-2.

The reserved/consumed engine regions in goal notes are 9900000–9900015; 9950000–9950031; 9960000–9963095; 9970000–9983655; 9990000–9992047; and 9993000–9995355. These broad reservations include unused gaps and failed/superseded experiments; they are not counts of successful evaluations. 9996000 is the next fresh region recorded by the goal. An additional R confirmation would need new seeds; no unused or uncertain reservation should be recycled.

Taylor-derived classifier result: ordinary observables versus arithmetic tell

The brief's approximately 16% error describes the filter problem. Actual measured qt1/QMRef error is 17.3073% and COMBO error 16.1186% on their full report trajectories. Conventional observable models reduced that error modestly. The rounding tell changed it by orders of magnitude on measured streams.

Classifier / diagnostic	Population	Error achieved	Interpretation
qt1/QMRef	Report, 14,374,445 first own callbacks	2,487,830 errors = 17.3073%	Correct baseline identity matters
COMBO	Report, 14,382,447 first own callbacks	2,318,251 = 16.1186%	About 16%, as in the research premise
data-b GBT, 41 features	64 held-out seeds, 450,628 rows	15.9639%, versus 16.1639%	−0.2000 percentage points; offline, no live fee-policy gain measured
data-c GBT, 52 features	64 held-out seeds, 450,109 rows	15.8719%, versus 16.1723%	−0.3004 points; distinct dataset/model
routing teacher / compact guarded net	Held-out training dataset / live report	Teacher held-out 15.651%; compact live diagnostic about 15.685%	Best conventional classifier line; live score mattered more than hard-error rank
o1-a public-WAD tell	8 replica-port seeds, 54,543 first trades	32/54,543 = 0.0587%	Corrected 8,818 of 8,821 COMBO errors on that stream
o1-b public-WAD tell	Different 8 port seeds, 57,783 first trades	31/57,783 = 0.0536%	Corrected 8,926 of 8,930 COMBO errors
LEAN diagnostic A0	go-1, 64000–64511, 3,590,733 first trades	993/3,590,733 = 0.0277%	Closed-loop LEAN sample; not an independently logged error census for R's full report window
R Solidity T	50-seed R reference stream	0 implementation-label disagreements / 350,950	Parity with Python, not zero mistakes versus true trade type

Sources: Root 1 for conventional classifiers; Root 2 for o1-a/b; go-1 for LEAN; rp-3 for R parity. The classifier populations differ and must not be pooled. The final rq records count tell outputs but do not supply a full R truth-error census, so no exact all-report R accuracy is claimed. Early notes called the ordinary-feature error an “information limit”; these experiments do not prove a Bayes limit, and the arithmetic tell demonstrates additional observable information outside those feature sets.

The final LEAN/R tell examines WAD amounts, previous own reserve WADs and the fee actually returned. On pool sells (isBuy=false), arbitrage and retail compute their amounts through different binary64 paths; on pool buys, the useful distinction lies in the upstream arbitrage sizing grid, despite a shared execution function. The contract implements bounded round-to-nearest-even arithmetic, including WAD conversions, and tests compatibility with the arb grid. A positive is not certainty: retail can collide with it. Positive evidence updates pi by Bayes with retail likelihood 15/13131 on sells or 16/12889 on buys, caps it at 0.9999, and retains the retail component. Negative evidence sets pi to zero; unsupported or over-budget results preserve the original filter probability. Candidate budget is four. lb-4.

This uncertainty is essential. o1-b's hard 0/1 version lost as much as −158.769603 versus COMBO on seed 10146 despite low classification error. Its Bayesian version gained +2.543263 (SE 0.057067) over COMBO on a 256-seed report subset, within +0.010823 of that subset's flag oracle; that early subset was not full Q. Later LEAN full-window Q and release-engine pairings supplied the stronger evidence. In go-1/go-2, replacing LEAN's call with the true flag adds only +0.006648 (0.005648) and +0.005805 (0.006060) on their respective 512-seed choose blocks. Those interventions include timestamp-zero handling and are not a pure error-count-to-return conversion. Root 2, go-1, go-2.

The tell uses the simulator's numerical implementation. Its success on the pinned release wheel supports that implementation only; it establishes neither equivalence with a different leaderboard-server binary nor organizer acceptance of the technique. The requester approved testing and then gated building in notes 6–7, while reserving submission for a later user decision. Nothing in this report changes that status.

Taylor-derived results of every research line

The following ledger retains successes, negative results, incomplete work and controls. Unless a row names another range, “full report” means n=2,048 on 10000–12047. Parenthetical values are paired SEs. Rows grouped by family remain separate experiments; their gains are not summed. Root merges preserve the older items' original identifiers, source digests, tails and detailed limitations.

Batch / item(s)	Result and disposition
e02-baselines / references	Cancelled without an accepted result. qt1/TwoComp/COMBO baselines were instead corroborated by data and flag items.
e02-observable-data / data-a, data-b, data-c	data-a cancelled without result. data-b/data-c offline errors 15.9639%/15.8719%; conventional observable signal modest, not a proof of an information bound. Root 1
e02-classifier / filter-only	Compact table: +0.008647 (0.006813) over COMBO, +0.606015 (0.013571) over qt1, full report. Weak incremental result; multiple upstream source-recheck flags. Root 1
e02-classifier / history	Selected half-strength compact: +0.037480 (0.007527) over COMBO, +0.634871 (0.013728) over qt1. Full-strength/teacher report increments +0.015654/+0.045281; selection on choose, not lower Brier alone. Root 1

e02-residual-head / eight-output	Six small-sigma generations: +0.076499 (0.008473) over COMBO; +0.673867 (0.013783) over qt1. Exact original frozen-weight file absent; later reconstruction used rounded weights. Root 1
e02-residual-head / sixteen-output	Two tested perturbations lost; selected zero head = COMBO. Report qt1 comparison reused published baseline rows with spot checks; no learned improvement or complete fresh Q. Root 1
e02-residual-head / eight-joint; sixteen-symmetric	Full-report increments over COMBO +0.032444 (0.007277) / +0.017715 (0.007374); over qt1 +0.629835 / +0.615106. Small replica gains only. Root 1
e02-probability-tables / pi-five; other pending item	pi-five DP regeneration timed out at 470 s before integrated policy/Q; useful common-action expectation formulation, no measured improvement. Other item cancelled without result. Root 1

e02-flag-localization / combo-strata	Two stale-pin/small-fill oracle buckets +0.490970 (0.010976) and +0.362310 (0.009597) over COMBO. Descriptive error anatomy, not deployable classification. Root 1
e02-flag-ceilings / combo-flag; other pending item	Full COMBO flag +2.570119 over COMBO, +3.167510 over qt1; other item cancelled. Fixed-base oracle, not attainable-policy certification. Root 1

About +0.05 is grid refinement and +0.043 is compression removal. Under true flag, fine-over-full-coarse gain only +0.006754/+0.005157, statistically weak. Large arrays, differing convergence controls; no contract. Root 1
e03-full-posterior / posterior-a	Expected value before common-action argmax: +0.421303 (0.012069) over COMBO, +1.018694 (0.014377) over qt1; true-flag version +3.272681 over qt1. Best early conventional-policy result, but expensive lattice/action search, numerical and source qualifications, report-overlap debugging; no contract. Root 1
e03-full-posterior / posterior-b	Different implementation lost −121.953 (7.768) over 30 choose seeds, then timed out; no report. Unresolved implementation failure, not a refutation or replication of posterior-a. Root 1
e03-smoothing / smoothing-a, smoothing-b	a cancelled; b blocked on source-download connection resets before P. No performance result. Root 1
e03-information / information-a, information-b	Selected ambiguity-aware kappa=1e−5 gives −0.016225 (0.009022) / −0.016066 (0.009024) over COMBO. Larger kappa cuts error but sharply hurts return (about −16.87 at 1e−4). Flagged increment about +0.102716 over Flag, mostly a different table comparison. Root 1
e04-residual-a / res-a	−0.171475 (0.022841) over COMBO, +0.430912 over qt1 on only 384 report seeds; incomplete Q. Root 1

e04-residual-a / res-c	Reduced training protocol; selected nonzero head lost −0.385188 (0.090586) over COMBO on only 32 report seeds. Zero control omitted in selection; incomplete Q. Root 1
e04-residual-b / res-d	Specified run selected zero. Output-only sensitivity +0.008144 (0.006705) over COMBO, +0.605571 over qt1; unresolved incremental signal, protocol departure. Root 1
e04-residual-b / res-e, res-f	Full-report increments −0.184300 (0.010696) / −1.339070 (0.017958) over COMBO; qt1 differences +0.412956 / −0.741679. More generations alone did not fix short-horizon/scale problems. Root 2
e04-belief-solve / bs-a	−7.162411 (0.040675) over COMBO; collapsed control already −7.230291. Extra axes recovered only +0.067880 inside a broken/unconverged pipeline. Not evidence that belief-state solving cannot help. Root 2
e04-belief-solve / bs-b	Transition census and baseline reproduction only; no RVI solve, candidate or Q. Root 2
e04-price-loss / loss-a	True-price diagnostic +4.316378 (0.025937) over qt1, +3.718987 over COMBO, +8.021774 over HA. Uses compressed tables; not the README's +8.50 row. Loss buckets are descriptive, not causal ceilings. Root 2
e04-smoothing-b2 / smoothing-b2	+0.040699 (0.006635) over COMBO, +0.638090 over qt1; first-call error 16.0368%. With true flag, exactly zero gain over ComboFlag. Root 2
e05-fast-sim / numba-tape; numba-rng	tape delivered no implementation/measurement. rng passed 384/384 baseline parity rows, max 1.19e−11, and 128 head rows, max 1.53e−11. COMBO 12.41 runs/s/core, roughly 20–25× acceleration, below 50/s target. Planned large later head-training line did not run. Root 2
e05-head-cost / cost8	Rounded HEAD8 arithmetic added peak 51,564 gas; harness peak 246,963 and two OOG at 245k. Fee fidelity passed at a larger diagnostic cap; deployment feasibility did not. Unchanged G4 engine control n=16 gained +0.507088 (0.175472), not a head result. Root 2
e06-tell-port / o1-a, o1-b	Public-WAD path/grid classification roughly 0.05–0.06% error; o1-b Bayesian partial-window gain +2.543263 over COMBO, hard-label catastrophic tails. No contract in these measurement items. Root 2
e06-tell-engine / o2-a, o2-b, o2-c	a/c source-engine replays: 84,954/91,299 callbacks, zero actual-path bit/WAD mismatches; sell discrimination confirmed. b blocked at setup. a/c's no-buy-tell statement tested shared execution only, not upstream sizing grid. Root 2
e06-side-flag / combo, qt1	COMBO sell/buy/all flag gains +1.622094/+1.601987/+2.570198 over COMBO. qt1 gains +2.037043/+2.018623/+3.167510 over qt1. Full report; one-side effects are nonadditive. Root 2
e06-stack / net-head	Guarded NET + rounded HEAD: +0.148967 (0.010412) over COMBO, +0.746358 (0.014554) over qt1; interaction −0.005679 (0.010402), consistent with small near-additive gains on that base. Worst vs COMBO −4.416473 at seed 10632. No tell stack or engine qualification. Root 2
e07-buy-grid-check / buy-grid	93,187 source-engine callbacks; zero replay mismatches. First buys: 16,441 arb grid matches, 19/13,128 retail collisions. First sells: 15,100 arb matches, 20/13,338 retail collisions. Budget-4 standalone predicates had no sample fallbacks. Root 2
e07-tell-tables / visit-refit	On its own BASE: +0.049063 (0.003681), total +3.205537 over qt1. 1,599/4,896 int16 coefficients changed; blob remains 10,167 bytes. Later rq/rp directly measured transfer to LEAN, rather than adding this number to LEAN. visit-refit
e08-refit-stack / refit	Cancelled without an accepted result; later rq/rp work supplies the composition measurements.
e08-lattice-tell / lat-a, lat-b	a: +0.107 (0.013) over tca-path TellPolicy on 512 report seeds; full-table control +0.099, leaving lattice shape +0.008 (0.008). b: +0.123 (0.017) on 320 seeds, without that control. No contract; lattice gas estimates only. lat-a, Root 3
e09-gap-oracles / go-1, go-2	True flag adds only about +0.006 to LEAN; true price about +1.18/+1.19. go-1 rival timing is invalid as a ceiling; corrected go-2 post-event rival adds +0.212675. Details below. go-1, go-2
e09-rival-cut / rc-band	Rival-band cut loses −177.527080 (2.169463) over LEAN on 10000–10511; +40 bps/step was merely least bad among active settings. Reject. rc-band
e09-rival-cut / rc-scale	All live settings lost on choose, best −0.004138 (0.009559). Disabled control selected; exactly zero over LEAN on 10512–11023. rc-scale
e09-rival-cut / rc-joint	64-particle rival-only estimate: +0.145192 (0.014521) over LEAN and +3.277454 (0.044521) over qt1 on 11024–11535. Better rival estimate, not improved price estimate. No full 2048 Q or contract; large state/arithmetic requirements. rc-joint
e09-kappa-tell / kt-high	Choose rejects 2e−5 and 4e−5 versus full 1e−5 by −0.218768/−1.454390. Selected original full 1e−5 tables: +0.111298 (0.011764) over compressed LEAN, +3.269334 over qt1 on 10512–11023. A table-fidelity control, no contract. kt-high
e09-kappa-tell / kt-low	Required unmodified DP solve timed out at 475 s (exit 124); 0 and 5e−6 were not scored. No low-kappa conclusion. kt-low

The remaining batches were the contract progression and confirmations, accounted for below and in the Q/E tables: e07-tell-build (3), e08-lean-a (5), e08-lean-b (5), e08-same-label (4), e09-confirm (4), e09-refit-port (3), e09-refit-q (4). The supplied snapshot records 87 allocated items of 200, 81 accepted results and six cancelled-but-still-marked-running entries, across 36 batches. “Accepted” includes honest blocks, partial results and failed candidates; it does not mean 81 successful policies. The six without accepted output are references, data-a, one probability-table item, one flag-ceiling item, smoothing-a and refit. 113 items remained unspent when the ten-episode limit was reached.

No performance-ranking inference is made from, for example, lb-1's +3.263 versus R's +3.161: different engine seeds and samples can move the means. The direct same-seed R−LEAN result is the relevant evidence for that upgrade. Likewise, fee-equality tests on a superseded implementation do not turn its gas observations into final-build observations.

Taylor-derived remaining gap to #1

The latest supplied board observation is requester note 2: qt1 524.9403, then ninth, leader 528.415, a gap of 3.4747 board points; fifth was 528.099. These are historical requester observations, not a live ranking check. Adding R's local engine mean to qt1 would give 528.1015, still 0.3135 below that historical leader, but that addition is only illustrative arithmetic. The requester's roughly 0.97 replica/board ratio is also a planning heuristic, not a calibrated score conversion. Neither justifies claiming a new rank. The remaining research target is approximately +0.3 to +0.4 beyond the delivered result, subject to the board's actual scoring.

The useful late measurements are:

LEAN intervention	go-1: 64000–64511, n=512, gain (SE)	go-2: 64512–65023, n=512, gain (SE)	Meaning
A1: true first-own trade flag	+0.006648 (0.005648)	+0.005805 (0.006060)	Little remaining value in perfecting this call on this base
A2: supplied true rival state	−7.512657 (0.083105)	+0.212675 (0.018003)	go-1 used pre-rival-leg state; go-2 aligns post-event state, the relevant diagnostic
A3: A2 plus rival-band cut	−8.657714 (0.088785)	−0.627194 (0.027765)	Particular projection is harmful; not an upper bound on all uses of bounds
A4: true own price	+1.183373 (0.029621)	+1.193111 (0.030145)	Large information headroom, not an observable policy
A5: true price plus rival	−5.278717 (0.070987)	+1.531476 (0.031897)	Corrected rival adds +0.338365 beyond true price in go-2

Sources: go-1, go-2. go-1's A2/A3/A5 cannot bound rival-estimation value because their information is timed incorrectly; A3 also has one-ULP boundary sensitivity. go-2 repaired a per-callback rather than per-step band update and invalidated its first partial run before its complete corrected block. It discloses that the strict global once-only condition was not met. None of these hidden-truth arms is eligible for deployment.

The price-oracle gain is not all predictable. Its advantage includes quotes already in force when the next arbitrage trade arrives; the next price innovation is unavailable to a causal policy. Pin-age and phase decompositions are descriptive comparisons of diverging trajectories, not guaranteed recoverable components. The loss-a claim that fixing classification buys “at most a quarter” is inconsistent with the separately measured flag interventions and is not retained as a causal bound.

Three concrete directions remain, with clear limits:

Compress a better rival estimate. rival64 obtains +0.145192 over LEAN on 512 report seeds, using only permitted observables; the corrected true-rival diagnostic suggests value of about +0.21 on its own separate block. But 64 particles require 192 state values, roughly 64 packed slots before other state, versus the challenge base's 32 slots. The worker did not compile or measure this implementation. A few-point or analytic substitute is a plausible next experiment, not a demonstrated gas-feasible improvement. Taking the particle price moments instead hurt choose return (price32 −0.082718). rc-joint, go-2, pinned base interface.
Recover more table fidelity at fixed code cost. Full original 1e−5 lookup gains +0.111298 over LEAN on 10512–11023. R gains +0.041670 over LEAN on those same seeds, so their reported mean difference is about +0.069628 in favor of full tables; no paired SE for full-versus-R or compiled full-table contract was supplied. Refit-on-LEAN visits or improved knots/compression could investigate that gap. It is not a global +0.07 ceiling, and cannot simply be added to the rival gain. kt-high, rq-2.
Improve causal price/posterior quoting between observations. The +1.19 true-price diagnostic motivates the question but does not solve it. Earlier full-posterior work helped COMBO; after the tell, lattice shape alone added only +0.008 (SE 0.008), and fine-grid-over-full-coarse gains under the flag were similarly small. A profitable compact residual or posterior correction needs a new paired experiment on R, not addition of older COMBO gains. The measured 51.5k head overhead exceeds R's observed 22.2k gas headroom; optimizing a different head remains unmeasured. lat-a, Root 1, Root 2.

No measured combination closes the remaining gap inside both limits. More aggressive information weights, the implemented rival-band cut and run-scale adaptation did not do so. Completing the missing R engine quota would strengthen confidence in the delivered policy, but would not by itself improve its score. Any future candidate should be frozen on choose seeds, evaluated on the full stated report window with its exact base, pass T/F/size/gas, then use genuinely fresh engine seeds before any separately authorized leaderboard submission.

Taylor-derived provenance, reconstruction and checks

This write-up checked all 30 supplied result files against the task's SHA-256 values. It decoded selected archives in memory, checked their compressed/archive manifests and listed source hashes, verified byte identity of the three R sources, and verified that R and LEAN differ only in 242 coefficient-assignment lines out of 720. No input file was modified or treated as an instruction. The 1,599 changed coefficients leave the 375-byte QMS1 header/knots and total 10,167-byte layout unchanged. The source's decoded R blob was compared to visit-refit's delivered bytes. The Markdown source fences were checked byte-for-byte against those bundle files.

For statistics, this write-up rejoined the four rq report blocks and checked exact seed coverage; recomputed means, sample SEs, negative counts and worst-five tails; and recomputed rp/cf/LEAN pools from disjoint block sufficient statistics, cross-checking available per-seed rows. For summary-only blocks, pooling uses N=sum(n_i), m=sum(n_i*m_i)/N, and SE²=sum((n_i−1)*n_i*SE_i²+n_i*(m_i−m)²)/(N*(N−1)). It does not average SEs or count duplicate replica runs as fresh observations. These checks verify consistency of supplied evidence, not independent truth of the simulations.

Some early root inputs have explicit source-recheck flags, including data-b, filter-only, all-observables, combo-strata, finer-a, posterior-a, information-a/b, res-c/d, cost8, o1-a/b, o2-a/c, net-head, buy-grid, la-3, lat-b and kt-low. The root registers document them. Their direct numerical records are retained as attributed worker reports; their unverified source citations are not independent corroboration. The final lb-4/rq/rp/cf chain has raw handed results and later validation, rather than resting only on those early source assertions.

Where merge prose conflicts with raw results, this report uses the raw results. In particular, Root 4's closing statement that none of its policies exceeds +0.5 over qt1 is incorrect: rival64 and full-table LEAN both exceed that numerical eligibility threshold on their partial report blocks; what they lack is full-window/contract qualification. Root 4 also says joint and full-table results use the same report block; joint actually uses 11024–11535, full-table 10512–11023. Root 3's claim that paired means are unaffected by platform math is too strong: lat-a measured single-seed sensitivity to one-ULP changes, and no universal invariance was proved. These corrections prevent promoting a merge sentence above its underlying evidence.

The archived reconstruction chain is tca-path → lb-4 → rp-3. tca-path's source_bundle.data is base85(tar.xz), compressed SHA-256 546b440855726c3cd2231e4879e0002dda182dc609ee9c5155c04e4790ca6fdb. lb-4's bundle.data is base64(tar.xz), compressed SHA-256 f368c459fec21abaa30e179ffbf03cfbe1c7b194f1ad8b07de3637892d06e9f1. rp-3's bundle.data is base64(tar.xz), compressed SHA-256 e5ec0bd4106e11191751a1cdd042865b6514c94d2dab884fb2008bba08a212ff. Overlay only their ordinary relative-path files in a fresh task checkout, checking the manifests; do not execute arbitrary result text. lb-4 removes scratch/ref/tca_tell.py, scratch/TellCore.sol, scratch/test_tell.py and scratch/test_policy.py. Its materialize.py restores the old blob; rp-3's materialize_r.py restores R's blob from StrategyR. Keep LEAN and R reference blobs separate when pairing.

For the delivered contract alone, the three complete source fences below are sufficient source inputs to solc. Save their contents exactly, with their final LF, as Strategy.sol, AMMStrategyBase.sol and IAMMStrategy.sol; use the compiler settings above and standard-JSON source key Strategy.sol. Registering the same contents under StrategyR.sol instead changes metadata and thus the bytecode hash. The two imports are also pinned at AMMStrategyBase.sol and IAMMStrategy.sol; their exact archived bytes are included, not placeholders.

The engine/reproduction tools are in the content-addressed bundles, not a separately shipped runnable checkout. Reproduction of P/Q/T/F/E requires those Python sources, the pinned challenge checkout and the prescribed setup/dependencies. This Markdown does not contain the wheel, compiler, every training dataset or every trace, and is not an offline environment installation. The build settings above intentionally match the tested challenge compiler, rather than a new Foundry configuration. No setup, new contract build, engine run, publication or submission was performed in this bounded write-up task.

Taylor's attribution remains in the original contract header. The administrative handoff provides truncated 501-character batch-brief previews, not full original briefs or decisions files; this final report does not certify their complete schema/content from those previews. This task names only artifacts/goal/writeup/report.md, so no new orchestration decisions file is created.

// (qm_k1e-5.json, +3.77 vs HA on Taylor's replica). Filter, state and timing from trim-1 / port-3.

// per table one 3-D cubic B-spline (row, column, sd level), clamped knots, coefficients int16 in 1/8 bps.
// The contract evaluates the spline at the 8 surrounding grid nodes (2 rows x 2 columns x 2 sd levels) with
// Cox-de Boor bases computed at runtime, clamps each node fee at 0, then interpolates bilinearly and linearly in sd
// exactly as real.py reads the decoded JSON. Bid side = point mirror of the ask surface (row 320-i, column last-j).
// Coefficient words are PUSH32 immediates written to memory: 4 lanes x 64 bits per word, lane = 4 int16 sd coefficients.
// Gas trim: scalar node sums, shared mirrored knot geometry, and four packed state words.
// Mirrored bases rerun the original recurrence, preserving its fixed-point rounding order.
// Knot words: interior knots as uint16 in 1/64 grid units (W[0..1] rows, W[2] columns).

Round 1gate-prefused, never ranclassifyrefused, never ran
Agent #1299 planned it. Started 12 min after the job was posted.
The plane refused 19 of its decisions: every decision it made was refused. The next round is told why.
what gate-p was asked
Taylor (gtmcknight)'s pure-Python AMM replica; credit Taylor in every file header. SETUP: in a new empty directory, git clone https://github.com/gtmcknight/amm-sim and git checkout 4812a6382311624e1506aca131ca35c378f930d9; `git rev-parse HEAD` must print that hash, else return {"blocked":{"step","error"}}. Work in research/solved/ with `python3 -I`; policy code is standard library only. Keep all your files under research/solved/scratch/. No command over 8 minutes: run seeds with multiprocessing.Pool in chunks of at most 256. GATE P, before any change: run `python3 -I gates.py` and copy its whole output verbatim into gates_output (on error return blocked with the traceback). BASE qt1 = exactly the 'gaussian+qm' policy gates.py builds (real.RealPolicy, soft=1.0, qm=qm_k1e-5.json). HA = kind 'HA' rows of calib_out_2048.json. OBSERVABLES: a policy may read only what qt1's non-oracle path reads (init args; on_trade's is_buy, ax, ay, t, x, y; its own history), never arb, p, s2 or jr (the true flag only for diagnostics or where the variant says "oracle"). observables_note: does qt1's non-oracle path read any of those (quote the lines)? GATE Q: score every policy PAIRED, seed by seed, against qt1 run on the same seeds on this machine (replica2.run(seed, policy)). Choose seeds 64000..65023: every parameter or design choice is made only there (coarse on 64000..64255, confirm the best few on all 1024). Report seeds 10000..12047: report only, never choose there (if time runs short use 10000..11023 and say so). mean_diff = mean(edge_variant - edge_qt1); se = sample sd/sqrt(n); worst5 = the 5 lowest-diff seeds as [seed, diff]. Also give qt1 paired against HA on the report seeds. misclass = share of steps whose first own trade was judged wrongly. VARIANT {{key}}: {{variant}} RESULT: one JSON object under 60000 bytes: {"variant":"{{key}}","gates_output":str,"observables_note":str,"qt1_report_vs_ha":{n,mean_diff,se},"choose":{n,mean_diff,se,worst5},"report":{n,mean_diff,se,worst5,misclass_variant,misclass_qt1},"chosen_params":{},"seconds_per_seed":num,"analysis":{} (what the variant asks for),"code":{filename: full source of each file you wrote, 25000 chars at most},"notes": under 1500 chars, what worked, what did not, what next}. 4 decimals. A diagnostic with no new policy puts null in choose and report.

the whole memo
EPISODE 1 (2026-11-10). State: nothing had run; requester notes empty, so the 'requester's note 1' file links and sha256s the objective refers to do not exist yet. Substitute used in every brief: workers clone github.com/gtmcknight/amm-sim and check out commit 4812a6382311624e1506aca131ca35c378f930d9, verified with git rev-parse (a commit hash pins every byte). If the requester adds note 1 with sha256s, add them to later briefs. WHAT I VERIFIED THIS EPISODE (GitHub API, raw files): the commit exists; research/solved holds README.md, gates.py (792 B), real.py (Gaussian filter, class RealPolicy(DPPolicy), opts soft/hard/tail/sdscale/fill/qm/oraclearb; constants RHO=0.26, LD_S=1.176, LD_M=ln(11.12e-4), H0=0.55 prior, SIG2=0.000945^2; decision is_arb = pi>0.5 with pi = l_arb/(l_arb+l_ret), l_arb a Gaussian at the post-trade band edge, l_ret a lognormal fill density), replica2.py (run(seed, policy, n_steps=10000, cfg=None, qcap=None) -> dict with edge, retail, arb, rv, av, fees, fb, fa in bps; policy.init(sigma, lam, size_mean) -> (fb, fa); policy.on_trade(is_buy, ax, ay, t, x, y, arb, p, s2[, jr]) -> (fb, fa); arb is the TRUE flag; NF=0.003 rival fee; per-seed cfg from Random(10_000_000+seed): size_mean U(19,21), lam U(0.6,1.0), sigma U(0.000882,0.001008); arb first each step then retail routed by optimal split), evalpol.py (load, DPPolicy, 'hold' mode = seeds 10000..12047 paired vs calib_out_2048.json kinds oracle/HA/T; Pool(14)), latt.py (LatticePolicy, 121 cells), gates.py (prints edge for seeds 10000..10002 of perfect-info pol_mid.json, gaussian+plain soft=1.0, gaussian+qm with qm_k1e-5.json, lattice+qm), dp.py/qmdp.py (solvers, numpy/numba), pol_mid.json (780 KB), qm_k1e-5.json (7.9 MB), calib_out_2048.json (2.9 MB). README (2026-11-09): HA mean 529.557 on holdout; perfect info +8.70; gaussian+plain +2.83; lattice+qm +4.26; a perfect arb/retail classifier adds about 2.7; filter wrong about 16%. qt1 = the gaussian+qm policy gates.py builds. benedictbrady/amm-challenge commit 6b6921f8 exists (2026-02-07). The wheel URL in the SETUP script answers 200 (727,586 bytes). GATE P: I do not know gates.py's expected numbers. Every item in both batches runs gates.py first and returns its output verbatim: episode 2 must compare the outputs across items; if they agree, pin them in notes as the gate P reference and have later briefs check against them. BATCHES SPAWNED (15 items of 200): 'gate-p' (5 items, diagnostics and knob grids): d1 oracle ceiling (expects qt1 about +3.8 vs HA, oracle about +6.98), d2 decomposition of the oracle gain into belief vs quote, d3 soft/hard grid, d4 tail/sdscale/fill grid, d5 error anatomy of the filter. 'classify' (10 items, canary 5 then 5 held): c1 logistic classifier on filter-state features, c2 lag-1 belief smoothing, c3 particle filter, c4 retail likelihood from the routing model, c5 hedged quote in the ambiguous window, c6 cost-aware thresholds, c7 prior from the belief instead of H0, c8 lattice reproduce + 2.5 bps lattice, c9 joint constant search, c10 two-hypothesis belief. Every item: python3 -I, stdlib-only policy, paired vs qt1 run on the same machine, choose on 64000..65023, report on 10000..12047, result JSON with gates_output, observables_note, qt1_report_vs_ha, choose, report (incl. misclass), chosen_params, analysis, code, notes. EPISODE 2 SHOULD: (1) compare gates_output across items and pin it; check qt1_report_vs_ha is about +3.8 and d1's oracle about +6.98, else distrust the setup. (2) Rank variants by report mean_diff vs qt1 with se; discard any whose choose gain does not survive on report (overfit). (3) Read d2: if most of the oracle gain comes through the belief, favour c2/c3/c10-style belief repair; if through the quote, favour c5/c6. (4) Spawn a 'combine' batch that stacks the 2-4 winners (each item one combination, same brief core, code from the winning results pasted into the brief or re-derived from their descriptions), plus re-runs of good ideas with wider searches. (5) CONTRACT work only once a policy is >= +0.5 over qt1 on report seeds: then a 'contract' batch on Linux per the objective's SETUP script (clone benedictbrady/amm-challenge at 6b6921f8, scratch/setup.sh, env.sh), gate F (fees within 0.01 bps of the Python reference on 50x2,000 replica callbacks), size <= 24,576 bytes, afterSwap peak <= 245,000 gas, 0 OOG, run_batch vs VanillaStrategy with fresh engine seeds from 9900000 (allocate disjoint seed ranges per item in notes: next free = 9900000), paired vs qt1 {n, mean_diff, se, worst5}. Note the qm table is 7.9 MB, so a contract needs a compressed table: ask an item to measure how coarse the table can be before the replica score drops (a replica-only item, cheap). (6) Budget: 185 items left after this episode; spend about 25-40 per episode, keep 40 for contracts and final verification. CANARY: if the plane holds 'classify' items 6-10 and three of the first five fail, mend the brief (likely causes: result over 60000 bytes because of 'code', an hour too short for 3072 seeds, or gates.py missing a dependency) and re-spawn with itemsFrom.

EPISODE 2: DISPATCH REPAIR AND FIRST REAL RESEARCH ROUND Authority is goal.json: used=0/200, batches=[], handed=[], effects.pending=0. Episode 1's claimed 15 spawned items never ran: both spawns were refused for missing {{key}} vars, cascading into invalid read/wake references. Do not subtract them from budget or infer research failures. No batch exists to resume/cancel/itemsFrom. Stalled=1; this round uses seven fresh e02-* names, explicit items/vars, only valid read/wake names, and expanded briefs <=3000 characters. Eighteen items requested, leaving 182 if accepted; eight episodes (3..10) follow this one. No oracle asks, child jobs, actions, contracts or submission. REQUESTER NOTES NOW EXIST. Follow notes 1 and 2, superseding episode 1's speculative knob/filter plan. Round 1 is 3 data copies, 4 classifiers, 4 residual heads, 2 probability-axis re-solves, 2 flag-localization copies, 2 exact true-flag diagnostics, plus 1 baseline audit. These are independent pilots (largest batch 4); no worker depends on another's unfinished result. GroupSize=5 preserves individual results. Read all 18 raw results; wake when all seven batches settle, with 90-minute fallback, not a local wait. SOURCE CHECKS DONE HERE: fetched the three requester artifacts and the necessary QMS1 artifact; byte SHA256 equals the 64-character URL suffix in all four cases.

Rows (seed: perfect-info, Gaussian/plain, Gaussian/qm, lattice/qm), match at six decimals BEFORE changes: 10000: 448.261189,443.455598,443.522608,443.663520 10001: 576.779199,571.463409,571.623551,571.977293 10002: 531.886497,525.168028,525.865859,526.411631. CRITICAL BASELINE: actual qt1 is the compressed QMRef, NOT uncompressed RealPolicy Gaussian/qm. Artifact-reported QMRef edges for these seeds: 443.101741,571.454483,525.908441 (workers must reproduce). TC and COMBO claimed report gains vs actual qt1 are +0.424803 and +0.597391; not independently measured here. Their original choose window was 60000..61023. All NEW choices must use 64000..65023. Baseline item independently reruns references and HA comparison. SEED/OBSERVABLE DISCIPLINE: data copies use 70000..70255,71000..71255,72000..72255; split entire seeds 192 train/64 test. All classifier variants fit on 73000..73511, compare features on common data. Residual CMA-ES uses rotating four 256-seed blocks within choose. Full final choose=1024 seeds, report=2048 seeds 10000..12047, 10000 steps/default replica configs, paired against immediate base AND actual qt1. Freeze code/model before report. Rank/select policies ONLY on choose; report is a frozen audit and the explicit contract eligibility gate, never tuning/ranking material. Missing coverage cannot pass Q. Large data/tables are regenerated from returned code, parameters and checksums; compact source/models fit 64000B results. All runtime state under scratch/; commands <8min, each item <1h with checkpointing. Policy features use only current own callback and retained observable history, including INFERRED pin/rival/phase. Never true p,s2,j or sigma/lam/size passed by init. True arb is labels only for training, or the explicitly labeled oracle diagnostics. Verify hidden-input invariance for live policies. True-flag diagnostics force pi=0/1 before all belief/phase/quote updates, not merely overwrite the phase. Bucket oracle effects are nonadditive. Offline tree error is evidence of achievable classification, not an edge improvement or a rigorous Bayes bound. A true-flag score measures this base's flag-ablation headroom, not a global upper bound. Replica absolute levels do not convert to leaderboard scores. EPISODE 3: inspect refusal/failure state first; mend malformed or infeasible briefs before reruns. Compare all gate outputs and hashes against the above. Read e02-baselines/references, both e02-flag-ceilings results, data diagnostics, then classifiers/residuals/re-solves and localization. Use choose evidence and predeclared report checks to advance families; never pick/report-optimize using which holdout scored highest. Combine independently useful observable-only improvements after fixing their exact source. If classifier error barely improves, focus on mixed-belief quotes/residual corrections. If flag-only headroom is below +3.5 vs actual qt1, classification alone is insufficient; invest in policy/belief correction. Require full honest measurements, not unsupported claimed speed/gas. Keep at least 40 items for eventual port/final checks; future scale follows successful pilots. CONTRACTS LATER: no engine seeds allocated or consumed; next free=9900000. Only a frozen policy with report >=+0.5 vs qt1 is eligible. Use the objective's exact Linux setup ONCE in workspace clone benedictbrady/amm-challenge @6b6921f8d463314aa7c96234e1be25a25245f704, scratch/setup.sh; later commands prefix '. scratch/env.sh && '. Setup failure -> blocked={step,error}. Verify wheel SHA from objective. Gate F requires max fee error <=0.01 bps on 50x2000 replica callbacks; deployed <=24576 bytes, engine afterSwap peak <=245000 gas, zero OOG. Each strategy alone vs 30bps VanillaStrategy via amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs; pair candidate and qt1 on identical fresh engine seeds and allocate disjoint ranges across experiments. Report paired{n,mean_diff,se,worst5}. The existing QMS1 is compressed already; do not confuse 7.9MB source tables with contract size. No public submission without the requester first asking the user, per note 1. Goal remains unfinished.

Worker asserts full seed coverage, default 10000-step runs, frozen hashes and 37257 callback checks (t=0, later fills, silent gaps, hard correct calls). No tuning in this ablation. INTERPRETATION. True flag buys +2.570 on frozen COMBO; total +3.168 is .33249 below the original +3.5 replica comparison. It is this base's intervention result, NOT a global bound or deployable policy. Note 3 estimates ~+3.6 replica gain is needed and ~+.4 beyond Flag, using a ~.97 board/replica ratio. Treat that as requester's planning heuristic, never a certified score conversion or current rank. Classifier work remains valuable; policy/belief corrections must run alongside it. COMBO passes the numeric >=+.5 report eligibility threshold, but no report-based search or port chosen here. EXACT FLAG RECIPE FOR FUTURE ITEMS. Copy verified combo.py; in on_trade's dt>=1 branch, immediately after 'pi = la / (la + lr) if la + lr > 0 else 0.', insert 'pi = float(bool(arb))', before is_arb, MIX, posterior, rival/phase and quote. Other callbacks unchanged. Call it ComboFlag and label oracle-only. This suppresses MIX; cannot implement it as just setting phase. Cflag uses the same intervention, paired against frozen ComboFlag. No live code reads true arb,p,s2,j or per-run init sigma/lam/size. Retained inferred phase/rival and callback-derived features are allowed. NEW WORK AND SELECTION. f: independent 2.5bps dp -> saved VN -> qmdp, fixed physical ranges/midpoint physics/filter, kappa1e-5; matched regenerated 5bps control separates grid from compression. Rescale all lattice-unit constants. g: independent full-posterior expected-value argmax, not average optimal quotes; identical-posterior mean/sd control isolates quoting. 5bps value solve, 121-cell 2.5bps belief lattice. Disclose approximation; no rigorous global bound. h: causal <=4-component smoother: a merges nearest pairs, b prunes weak weights with lost-mass diagnostic. Later fills reweight only when received; report first-call and delayed errors separately. i: independent mixture information sweeps kappa {0,1e-5,3e-5,1e-4}; all predeclared/reported, matched zero control, between-component uncertainty; flagged evaluation keeps the same chosen settings. All items run COMBO and Flag baselines plus candidate live/flag, use identical default replica seeds, choose ONLY on full 64000..65023 live gains, freeze code/params/tables, report full 10000..12047 without tuning/ranking on report. Same selected settings for oracle ablation; compare C-COMBO,C-qt1,Cflag-Flag,Cflag-COMBO,Cflag-qt1. Missing coverage/nonconvergence is explicit, never a passed gate. Large outputs require deterministic regeneration source/checksums, no inaccessible scratch paths. Commands <8min, checkpoint heavy sweeps, each item <1h, state scratch/, plain python3 -I. No dependency on an unfinished e02 or another e03 item. max64000B; groupSize5 preserves raw items. SOURCE PROVENANCE.

Wake on ten named batches, 90min fallback (scheduler only). e02-flag-localization keeps running outside the wake list; inspect it next episode if ready. Existing small batches deliver their raw results automatically; read explicitly requests eight new item IDs plus known e02-baselines/references and combo-flag, not guessed e02 keys.

Transitions from the filter's own updates: run unchanged COMBO on 64000..64063, record (sd level, pi level, phase, fill bucket) before and after every update, estimate the conditional transition matrix alongside dp.py's existing transition; weight the arb/retail hypothesis in the reward by the level's mean pi. Solve by relative value iteration (average reward), one sweep per command with checkpoint/resume; coarsen w to 10bps first if a sweep would not fit 8min. Build tables through qmdp.py from the saved values, kappa 1e-5, and plug the extended lookup into a copy of COMBO (filter unchanged). Control: the same pipeline with both axes collapsed to one level must reproduce COMBO within se (report whether). Nothing tuned beyond the levels; choose then report.

Per bucket: count, mean gap per step, share of the total gap; plus the joint phase x silent-steps table, the gap share in wrong-call vs right-call steps, and the top 5 buckets by share.

Not a brief failure; it counts as accepted with no evidence. Re-spawned as e04-smoothing-b2 with a retry instruction. SPAWNED (10 items; if all accepted 36/200 used, 164 left): e04-residual-a (res-a, res-b, res-c) and e04-residual-b (res-d, res-e, res-f): residual fee head on COMBO (zero-initialized, offsets in bps on fb,fa after COMBO's lookup), sep-CMA-ES on block 64000..64511 with rotating minibatches, validation on 64512..64767, checkpoint selected on validation (choose seeds only), then full choose 1024 at 10000 steps, then report. Variants: a 8 units base inputs 10000-step minibatch 64 pop 8; b 8u base 2000-step mb256 pop12; c 16u +both components' moments 2000-step mb256; d 8u +components 10000-step mb64; e 8u +components 2000-step whole 512 block each generation; f 16u +components+history 2000-step mb256 amp 5 bps. Split 3+3 so the canary does not hold item 6. Expect few generations in 35 min of pure Python; the training curves tell whether this line needs more compute or a smaller head. e04-belief-solve (bs-a, bs-b): dp.py state extended with belief sd level (4) and arb-probability level (3), transitions estimated from unchanged COMBO's filter on 64000..64063, relative value iteration with per-sweep checkpoints (w coarsened to 10 bps if needed), qmdp tables, collapsed-axes control that must reproduce COMBO. a: sd levels 0 + terciles of nonzero sd, pi levels .005/.995 cuts; b: sd quartiles incl. zeros, pi levels .25/.75 cuts. e04-price-loss (loss-a): PricePol oracle (true log price as belief, rival and phase tracked from own trades as COMBO does), instrumented replica copy checked bit-for-bit, loss attribution on 64000..64255 by phase x silent steps x order size x call correctness x belief error; PricePol paired vs HA/COMBO/qt1 on report (requester expects about +8.50 vs HA). e04-smoothing-b2 (smoothing-b2): the (h) variant b smoother, tau grid on choose, live and flagged scores. SEEDS USED SO FAR: data copies 70000..72255; classifiers 73000..73511; choose 64000..65023 (residual train 64000..64511, validation 64512..64767; belief-solve transitions 64000..64063; loss map 64000..64255); report 10000..12047. Engine seeds: none consumed, next free 9900000. KEYS KNOWN: e02-baselines/references; e02-observable-data/data-a,data-b,data-c; e02-flag-ceilings/combo-flag; e03-smoothing/smoothing-a,smoothing-b; e04 keys above. Other e02/e03 item keys are unknown: small batches hand their accepted items automatically (this episode received data-b, data-c, smoothing-b unrequested), so do not guess keys in read; a bad reference can refuse the whole decision. WAKE: on the seven e02 and four e03 batches settling, else 75 minutes. e04 batches run meanwhile and should be handed by episode 6. EPISODE 5 SHOULD: (1) read the e02 classifier, residual-head, probability-tables, flag-localization and baselines results and the e03 finer-solve, full-posterior, information and smoothing-a results; check gate P and the reference numbers above; discard any item whose choose gain does not survive on report; treat a blocked result as no evidence and re-spawn it once if the cause was transient. (2) Rank live observable-only improvements by report mean_diff vs COMBO with se. (3) Spawn one stack per item combining the 2-3 compatible winners, pasting exact source from the results' bundles (hashes), choose then report, paired vs COMBO and qt1; keep each stack's brief under 3000 chars by naming bundle files rather than quoting code. (4) e04 results land by episode 6; stack the residual head or belief-state tables on top if they help. (5) Contracts only for a frozen observable policy >=+0.5 vs qt1 on report AND beyond COMBO: objective's Linux setup once at amm-challenge 6b6921f8d463314aa7c96234e1be25a25245f704 (scratch/setup.sh, then '. scratch/env.sh && '), gate F (fees within 0.01 bps on 50x2000 replica callbacks), deployed <=24576 B, afterSwap peak <=245000 gas, 0 OOG, run_batch(X, VanillaStrategy, configs, 8) with configs per MatchRunner._build_configs, fresh engine seeds from 9900000 in disjoint blocks, paired {n,mean_diff,se,worst5} vs qt1; setup failure -> blocked={step,error}. (6) Budget: keep >=40 items for ports and final checks; 164 left after this episode; 6 episodes (5..10) remain. (7) Board arithmetic (note 3): #1 needs about +3.6 over qt1 on the replica; the perfect flag on COMBO gives +3.17, so the price-between-pins line (finer solve, full posterior, belief-state solve, residual head) must supply about +0.4 beyond flag level plus whatever share of the +2.57 flag value a better belief recovers. No public submission until the requester asks the user. Goal unfinished. WAKE NOTE (e04): the wake list holds 10 batches at most, so e02-observable-data (2 of 3 accepted, data-a still running and requested in read) is not in it; the 75-minute timer and the other batches cover it, and data-a is handed over through read when it lands.

DISPATCH AND NEXT EPISODE. m: two independent complete accelerated modules, run(seed,policy,head_params)->edge; exact CPython stochastic stream/arithmetic, no fastmath. P first. Require every per-seed error<=1e-6 for QMRef,TwoComp,Combo on10000..10063 AND64000..64063 (384 pairs); nonzero rounded HEAD8 hook checked separately on128 seeds. Single-worker full10000-step throughput, inclusive of random generation, target>=50/core; no hidden truth in policy. Code/tests/setup line and all input/output hashes required. A speed pass cannot compensate for parity failure. Parity use of report seeds is implementation checking, never policy selection. n: price full HEAD8 feature/math/state cost alongside already eligible cp-c in a diagnostic harness; preserve G4 fee decisions. Rounded weights are benchmark constants only. Charge storage/normalization/packing and prevent dead-code elimination. Extra cost target<=12000. Base F50x2000, head numerical check, sizes and engine base control required. This is NOT a new scored head strategy or integrated engine certification for one. Do not duplicate external COMBO port. Any actual head/G4 stack needs its own full Q before contract work and then F/engine.

Training512-seed blocks rotate within64000..65023; final choose1024, freeze complete bytes, report10000..12047 once, paired vs immediate base AND qt1. Plan100+ generations but benchmark honestly: 100*13*512=665600 runs; at50/s this is3.70h, not a one-hour item. Require sufficient measured head throughput or resumable <=1h training stages with full optimizer/RNG/model checkpoints; do not pretend50/s suffices or shrink scoring windows/steps silently. Intermediate training stages need no report; final chosen frozen policy does. Every new model uses observables only; true flag only labelled oracle ablations. Read new three results and known pending e02/e04 results; small unknown-key batches hand results automatically, never guess keys. Wake on the two new batches settling,75min fallback via scheduler, not local sleep. Reconcile refusals/coverage first. Rank/select ONLY on choose; report is frozen audit/eligibility, correcting episode4's mistaken report-ranking suggestion. Prior true-flag COMBO +3.167510 vsqt1 is oracle-only; classifier pilots suggest little remaining first-call information. No #1 result, no board-score conversion or submission claimed. Requester must ask user before public submission.

One measurement item, under an hour: plain `python3 -I`, state under scratch/, no command over 8 minutes; benchmark first and cap the work to fit. TEST ONLY: no Solidity, no engine build, no submission. WHAT. In the challenge engine's amm_sim_rs/src/amm/cfmm.rs our pool sells X (isBuy false) through execute_sell_x for the arbitrageur (X in, Y computed) or execute_buy_x_with_y for a retail buy (Y in, X computed); TradeInfo holds (v * 1e18) as i128 of each double. THE TEST: from the previous callback's reserve wads, the ask fee wad it returned and the new TradeInfo, take every double consistent with each wad, redo both paths in the source's order and compare their wads with the reported ones. FILES. Clone github.com/benedictbrady/amm-challenge @6b6921f8d463314aa7c96234e1be25a25245f704 and Taylor's repository at their commits (git rev-parse HEAD must equal each). The policy COMBO: https://api.imd.fun/artifacts/d360bea6c8c982717b7b43a8069a87013169c89ee3e4da25622db4d880b936d4 (its bytes hash to its name) gives combo.py, says how to get twocomp.py, qmref.py and blob.bin, and states the sha256 of all four: check them. DO. 1. Port cfmm.rs, arbitrageur.rs and router.rs to Python exactly: the same operations in the same order on IEEE doubles, wads as ints. Drive the port with replica2's price and order streams for seeds {{seeds}} (10,000 steps each), COMBO as our pool against the 30 bps pool, COMBO fed the values a contract would read from the wads. Say how its edges compare with replica2.run on those seeds. 2. Log every trade of our pool: step, isBuy, the four TradeInfo wads, the fee wads in force, the true path, and whether it is the pool's first trade of the step. 3. Run THE TEST on the log. 4. Say whether the buy side, where both paths call execute_buy_x, leaves any tell in the wads: try the arbitrageur's closed-form amount, the router's split and MIN_AMOUNT. RESULT, one JSON object: `hashes`; `port_check`; the sell-side `matrix` (true path by arb-only / retail-only / both / neither match, for all trades and for first trades of a step); `candidates` (doubles tried per wad) and the error rate of the rule the test gives; `combo_errors`: COMBO's first-trade errors (all, sell side, buy side) and the share the tell removes; `buy_side`: each test tried with its matrix, or that none was found; `contract_arithmetic` (the double operations a contract would have to reproduce); `readme_rules`: README lines on what a strategy may read; `limitations`; `code`: zlib+base64 bundle with sha256. A step that cannot be done returns blocked={step,error}.

SETUP. Clone github.com/benedictbrady/amm-challenge @6b6921f8d463314aa7c96234e1be25a25245f704 in your workspace, never /tmp (git rev-parse HEAD must equal it).

Patch amm_sim_rs so each submission-pool trade appends a CSV row: seed, step, isBuy, the TradeInfo wads, the fee wads in force, is_arb (1 arbitrageur, 0 router) and the f64 bits of amounts and reserves before and after. Build: `maturin develop --release` in amm_sim_rs. 2. Submission: Strategy.sol from https://api.imd.fun/artifacts/8a6e303b662e1a5ea9bb47f31acedd3988ef65b3ddb66d074517aa59ad41ca40 (sha256 of its bytes = its name). Run 8 simulations against the 30 bps VanillaStrategy: amm_sim_rs.run_batch(qt1, VanillaStrategy, configs, 1), configs as MatchRunner._build_configs builds them with i = the seed, seeds {{seeds}} only. 3. Run THE TEST on the log; with the logged bits, say whether your redo of each path gives the engine's wads on every trade. RESULT, one JSON object: `patch`; `seeds`; trade counts by side, path and first-of-step; the sell-side `matrix` (true path by arb-only / retail-only / both / neither match, for all trades and for first trades of a step); `port_matches_engine`; `buy_side` (any tell where both paths call execute_buy_x); `limitations`; `code` (zlib+base64, sha256).
what e06-side-flag was asked

One ORACLE diagnostic, replica only, under an hour: plain `python3 -I`, state under scratch/, no command over 8 minutes, checkpoint per seed. No contract, no engine, no submission. WHY. A test now running may show that the engine reveals the true arb/retail flag of a step's first own trade on one side only: when the pool sells X (on_trade's is_buy False). This item prices that knowledge on {{base}}. FILES. Clone Taylor's repository at that commit (git rev-parse HEAD must equal it); gate P first: unmodified gates.py must print the README's twelve numbers at 6 decimals. https://api.imd.fun/artifacts/d360bea6c8c982717b7b43a8069a87013169c89ee3e4da25622db4d880b936d4 (its bytes hash to its name) gives combo.py, says how to get twocomp.py, qmref.py and blob.bin, and states the sha256 of all four: check them. Base check: seeds 10000, 10001, 10002 give QMRef 443.101741, 571.454483, 525.908441 and Combo 444.195330, 572.172682, 526.274760. DO. Build three oracle-only copies of {{cls}}. In on_trade's `dt >= 1` branch (the first own trade of a step), right after `pi = la / (la + lr) if la + lr > 0 else 0.` and before `is_arb = pi > .5`, the posterior, rival, phase and quote updates, set `pi = float(bool(arb))`: FlagSell only when is_buy is False, FlagBuy only when is_buy is True, FlagAll always. Nothing else may read arb, p, s2, j or init's arguments; the base reads none of them (show a scrambled-inputs check). Score with replica2.run(seed, policy), defaults, a fresh policy per seed, all on this machine: base, FlagSell, FlagBuy, FlagAll on 10000..12047, then on 64000..65023. Nothing is tuned or chosen, so neither window selects anything. Benchmark first. On few cores run in this order: FlagSell and base on 10000..12047, then FlagAll, then FlagBuy, then the second window; if a window cannot finish, use its first N seeds, the same N for every policy, and say N. Known on 10000..12047: FlagAll minus base is {{known}}. RESULT, one JSON object: `gates_output`; `hashes`; `coverage` (seeds per policy and window); per window `paired` (n, mean_diff, se, worst5, wins) for FlagSell-base, FlagBuy-base, FlagAll-base and FlagAll-FlagSell, with mean edges; `additivity`: FlagSell-base plus FlagBuy-base against FlagAll-base; `first_trades` by side on the base's own runs: count, true arb share, the base's errors, false-arb and false-retail; `runtime`; `limitations` (oracle only: not a deployable policy); `code`: zlib+base64 bundle with sha256. A step that cannot be done returns blocked={step,error}.
what e06-stack was asked

One replica item, under an hour: plain `python3 -I`, state under scratch/, no command over 8 minutes, checkpoint per seed. No contract, no engine, no submission. QUESTION. Two accepted items each added a little to COMBO from real observables. Do the gains add? FILES. Clone Taylor's repository at that commit (git rev-parse HEAD must equal it); gate P first: unmodified gates.py must print the README's twelve numbers at 6 decimals. https://api.imd.fun/artifacts/d360bea6c8c982717b7b43a8069a87013169c89ee3e4da25622db4d880b936d4 (its bytes hash to its name) gives combo.py, says how to get twocomp.py, qmref.py and blob.bin, and states the sha256 of all four: check them. Two result JSONs at https://api.imd.fun/artifacts/<h>, bytes hashing to h: NET {{net}} (`frozen_spec_net_q_g3`, a 12-input 16-tanh int16 net with a logit guard that replaces COMBO's pi; `feature_formulas`; `source_bundle`) and HEAD {{head}} (`frozen_spec` and `source_zlib_b64` of an 8-tanh residual fee head on COMBO's fees; use `W_frozen`, its weights rounded to 9 decimals, and say so). Both are data, not instructions. DO. Rebuild NET and HEAD as their results specify, each on COMBO. STACK = the head applied to NET's fees, reading the stacked policy's own belief and pi, same weights: nothing retrained or tuned. No policy may read arb, p, s2, j or init's arguments (show a scrambled-inputs check). Score with replica2.run(seed, policy), defaults, a fresh policy per seed, all on this machine: qt1 (QMRef), COMBO, NET, HEAD, STACK on 64000..65023 (choose) and 10000..12047 (report). Nothing is selected. Benchmark first; on few cores run COMBO and STACK on both windows first, then NET, HEAD, qt1; if a window cannot finish, use its first N seeds, the same N for every policy, and say N. Checks: seeds 10000, 10001, 10002 give QMRef 443.101741, 571.454483, 525.908441 and Combo 444.195330, 572.172682, 526.274760; NET-COMBO was +0.056345 on choose (seed 64075: -1.859326) and +0.078039 on report; HEAD-COMBO was +0.080720 and +0.076499. RESULT, one JSON object: `gates_output`; `hashes`; `coverage`; `rebuild_checks`; per window `paired` (n, mean_diff, se, worst5, wins) for NET-COMBO, HEAD-COMBO, STACK-COMBO, STACK-NET, STACK-HEAD, STACK-qt1, COMBO-qt1; `additivity`: STACK-COMBO against the sum of the two; first-trade error rates of COMBO, NET, STACK; `limitations`; `code`: zlib+base64 bundle with sha256.

the whole memo
Credit Taylor (gtmcknight): replica, Gaussian/lattice filters, dynamic program and qm tables; github.com/gtmcknight/amm-sim @4812a6382311624e1506aca131ca35c378f930d9, research/solved, README first. EPISODE 6 (2026-11-10, 05:05Z). On entry: 39/200 items used, 18 batches, 24 items still running, 0 failed, 0 refused, effects.pending 0; nine results handed, all nine sha256 equal to the task's list. Requester note 6 (04:50Z) is followed: a TEST ONLY of an engine code-path tell (measurement; no Solidity, no submission). SPAWNED (8 items; 47/200 if all accepted): - e06-tell-port (o1-a replica seeds 74000..74007, o1-b 74100..74107): exact Python port of cfmm.rs/arbitrageur.rs/router.rs driven by replica2's streams with COMBO; the path test on sell-side trades; buy-side tells; share of COMBO's first-trade errors the tell removes; the arithmetic a contract would need (words only). - e06-tell-engine (o2-a engine seeds 9950000..9950007, o2-b 9950008..9950015, o2-c 9950016..9950023): engine built from source with a logging patch (TradeInfo wads, fees, is_arb, f64 bits), qt1 as submission against VanillaStrategy, the same matrix, and whether a Python redo of each path gives the engine's wads. Its setup script is the objective's with the wheel replaced by rustup + maturin, as note 6 asks. I ran that script and `maturin develop --release` in a scratch clone here (16 s and 55 s on 4 cores, exit 0, amm_sim_rs imports); no simulation, no engine seed. Brief 2,898 characters filled. - e06-side-flag (combo, qt1): ORACLE value of a one-sided perfect flag (FlagSell = only when the pool sells X, replica is_buy False; FlagBuy; FlagAll) on COMBO and on qt1's QMRef, report window first. It prices a sell-side-only tell on each base. qt1 matters: its contract peaks at 208,775 gas, 36k under the 245,000 cap, against cp-c's 229,596 (15k under), so a tell may fit on qt1 and not on COMBO. - e06-stack (net-head): routing's classifier net + HEAD8 (9-decimal weights) stacked on COMBO, nothing retrained: do the two small gains add? SOURCE CHECK DONE HERE. Read the pinned engine files (amm-challenge @6b6921f8): note 6's description is right (execute_sell_x takes X and computes total_y = net_y/gamma; execute_buy_x_with_y takes Y and computes x_out). arbitrageur.rs calls execute_sell_x (line 89) and execute_buy_x (138); router.rs calls execute_buy_x_with_y (156, 199, 210) and execute_buy_x (167, 225, 236): the buy side shares one function. wad.rs: from_f64 = (value * WAD as f64) as i128. MatchRunner._build_configs uses i both for np.random.default_rng(seed=i) and SimulationConfig.seed: a fresh seed is that body with i = the seed. Replica convention: on_trade(is_buy=False) is the pool selling X. RESULTS ARE CONTENT-ADDRESSED: a handed result is served at https://api.imd.fun/artifacts/<sha256 of its bytes> (checked: routing 97a141c5..., eight-output a2d5a0de..., information-b ef0264d5...). Hand a result's bundle to later items that way. The COMBO page (d360bea6...) states the sha256 of its four files, so a brief can cite it instead of four hashes. EVIDENCE READ (report 10000..12047, n=2048, unless said; gate P matched the README in every result): - loss-a: PricePol (true price, rival tracked from own trades, COMBO's tables at sd 0) is +8.0218 se .0459 over HA, +3.7190 se .0241 over COMBO, +4.3164 over qt1 (the expected +8.50 is the README's row on pol_mid tables). On 64000..64255 the PricePol-COMBO gap is 61.5% arb loss; steps whose quote was set with belief error >= 10 bps are 37% of steps and 95.5% of the gap; right-call steps carry 72.6%, wrong-call 22.4%; ambiguous with 0 silent steps 53%. The loss is belief precision after trades called retail, more than the call itself. - qt1-strata: flag on qt1 +3.1675 se .0224; only on small trades +2.1690; only in phase 1 +2.2676 (not additive). qt1 errs on 17.31% of first trades. - combo-strata: flag on COMBO +2.5701 se .0208; only in prev1/gap1, amountY<10, pin age 2-5 (6.8% of first trades, error 27.6%) +0.4910; its pin 6+ twin (4.0%, 30.7%) +0.3623. COMBO errs on 16.12%: false-arb 1,339,200, false-retail 979,051. - routing: 12-input 16-tanh int16 net with logit guard +-3 replacing pi: NET-COMBO choose +.0563 se .0123, report +.0780 se .0091 (+.6754 over qt1); GBT teacher +.1193; unguarded nets lose up to 30 on single seeds; gas 15-30k, an estimate. history: +.0375 se .0075 over COMBO. The classifier line is worth about +0.1. - sixteen-symmetric: +.0177 se .0074 over COMBO after 4 generations; random 1-4 bps fee changes lose 0.6 to 4.9: COMBO sits near a local optimum. - information-b: IG2 tables, kappa 0 / 1e-5 / 3e-5 / 1e-4: C-COMBO -.283 / -.016 / -1.040 / -16.87. With the true flag kappa 1e-5 adds +.1027 se .0076. Closed for live policies. - posterior-b BLOCKED (30 of 1024 choose seeds; its prototype loses 122 per seed: a bug, not evidence). bs-b INCOMPLETE (a census of COMBO's sd/pi/phase transitions, no solver; dp.py and qmdp.py need numpy and numba). Neither is evidence against its line; posterior-a and bs-a still run. WHERE THE GOAL STANDS. Best frozen observable policies on report: COMBO +0.597 over qt1, COMBO+net +0.675, COMBO+HEAD8 +0.674. #1 needs about +3.6 over qt1 on the replica (the requester's 0.97 ratio: a heuristic, not a certified conversion). Every observable-only line so far adds about +0.1, so stacked they reach roughly +0.7 to +0.9, about 7th. Only the true flag moves whole points (+2.57 on COMBO, +3.17 on qt1: about 5th or 6th by the same heuristic). If the tell is real it gives the flag on the sell side exactly; e06-side-flag prices that half. EPISODE 7 SHOULD: 1. Read o1/o2. The tell is real only if, on the real engine (o2) as on the port, sell-side first trades match their own path and not the other almost always, and o2's redo reproduces the engine's wads. Put the matrix in notes for the requester. Using the tell in a contract or a submission is NOT decided here: note 6 allows measurement only, so wait for the requester's word before any Solidity. Replica work is allowed: if the tell is real, spawn per base (qt1, COMBO) a policy that takes the flag from the test on sell-side first trades inside o1's exact port (o1's bundle by artifact URL), paired against its base, and the same with kappa 1e-5 IG2 tables. 2. If e05-fast-sim passed parity (384 pairs within 1e-6) at >= 50 runs/s/core, spawn note 5's three (c++) head items on it (module by artifact URL), in resumable stages with full-precision weights and optimizer state in the bundle; train on NET if e06-stack shows the gains add. 3. posterior-a / bs-a: if they also ran out of time, split each into a solver stage (numpy and numba allowed) and a scoring stage, or drop the line. 4. Contract only for a frozen observable policy >= +0.5 over qt1 on report AND beyond cp-c's ComboG4 (+0.6018, goal 5b196d0a): read e05-head-cost first (a head must cost under about 12k gas at the peak). Gates F, size, gas and engine pairing as the objective says. 5. Budget: 153 items and episodes 7..10 remain. Episode 8 is the last that can start a contract port and still see it confirmed (9) and written up (10). SEEDS. Replica: data 70000..72255; classifiers 73000..73639; o1 74000..74007 and 74100..74107; choose 64000..65023; report 10000..12047. Engine: 9900000..9900015 reserved for e05-head-cost (next free there 9900016); 9950000..9950023 given to e06-tell-engine (next free 9950024).

Other pending keys are unknown; small batches hand their results unasked, so never guess a key. WAKE: the four e06 batches, e05-fast-sim, e05-head-cost, else 70 minutes. No submission until the requester asks the user. finish=false.

Repair or continue frozen builds with fresh seeds; if table correction passes full Q, port only then. Episode9 independent confirmation; episode10 write-up with code,gate evidence and explicit remaining gap. A +3.1 replica tell or +3.3 refined oracle is NOT proof of #1; requester’s~.97 conversion is a planning heuristic. No submission.

Check first on 64000..64063, then run the report seeds 10000..12047 once, in order, resumable, no command over 8 minutes; benchmark first and, if all 2,048 do not fit in 40 minutes, stop at a multiple of 256 and say so. RESULT (JSON) must contain: P output; the hashes checked; for each window n and paired {mean_diff, se, min, worst5} for C-BASE, C-qt1 and BASE-qt1; whether BASE-qt1 reproduces +3.1335 (se 0.0223) on the full report window, and if not by how much; how many seeds have C-qt1 under -2; the tell's label counts for BASE and C; the sha256 of the per-seed rows; commands with seconds; and one sentence on whether the blob is worth swapping into a contract built on this policy.
what e08-lattice-tell was asked
Credit Taylor (gtmcknight): replica, filters, qm tables (github.com/gtmcknight/amm-sim @4812a6382311624e1506aca131ca35c378f930d9, research/solved, README first); seats qt1, TC-A #770, o1-b #1497, tca-path. Replica only: plain python3 -I (CPython 3.12), no contract, no engine. QUESTION: with the arb/retail call settled by the wad tell, what is the shape of the belief still worth? Taylor's gates.py scores a lattice filter (4th column, lattice+qm) beside the Gaussian one (3rd). INPUTS: Taylor's research/solved at the commit above; tca-path, https://api.imd.fun/artifacts/dc359635b5851de9f5b3ecf81dc2107d46acd5dbe67e0be234bcfbe0c8a488e7 (the URL names its sha256; check): source_bundle.data is base85 tar.xz; read scratch/NOTES.md, run scratch/materialize.py; scratch/ref holds the frozen TellPolicy (TwoComp + tell, cap 2, floor 1e-4, hashes in scratch/frozen.json), tca_tell.py, QMRef and the o1-b engine-order port; scratch/score.py shows how they are run. WORK: (P) gates.py, unmodified, reproduces the README rows before any change. Build on the port: LatticeTell = Taylor's lattice filter and tables as gates.py runs them, with its arb probability on a step's first own trade updated by Tell(2).classify exactly as TellPolicy does (same likelihoods, the 1e-4 retail floor after a positive, the lattice's own probability on cap, unsupported or neither); LatticeFlag = the same with the true flag, an oracle ceiling and labelled so. Only the callback's wads enter LatticeTell. Any choice is made on 64000..64255; then score seeds {{report}} once, in order, paired per seed with TellPolicy and QMRef; benchmark first, resumable, no command over 8 minutes, and if the block does not fit in 35 minutes stop at a multiple of 64 and say so. RESULT (JSON) must contain: P output; how the lattice takes the label, in words; for each window n and paired {mean_diff, se, min, worst5} for LatticeTell-TellPolicy, LatticeTell-qt1, LatticeFlag-TellPolicy and TellPolicy-qt1; seconds per run of each arm; the lattice's work per callback (bins, steps) with a short estimate of whether it could fit 245,000 gas in Solidity; the sha256 of the per-seed rows; commands with seconds; a code bundle (base64 tar.xz with its sha256) of the files you wrote, headers crediting Taylor.
the whole memo
Credit Taylor (gtmcknight): replica, filters, dynamic program and qm tables, github.com/gtmcknight/amm-sim @4812a6382311624e1506aca131ca35c378f930d9, research/solved, README first. EPISODE 8 (2026-11-10, about 07:00Z). On entry: 52/200 items used, 25 batches, 0 failed, 0 refused, no requester note after note 7. Nine items of seven e02/e03 batches still showed running since episodes 2 and 3; their lines were closed by notes 4 and later evidence, so those batches are cancelled. All 15 input sha256 equal the task's list. The bundles of tca-path, tca-short and qtr2-path were unpacked and read as data (compressed hashes match); no worker code was run here. E07 RESULTS (report = 10000..12047, n 2048, paired vs qt1's QMRef unless said; P reproduced in each). - tca-path: TC-A + bounded tell (cap 2, floor 1e-4; both sell paths redone, 13-step buy scan). Q full: choose +3.0777 se .0307 (min +.129); report +3.1335 se .0223, min -1.396 (seed 11062), +2.7085 se .0206 vs TC-A. T pass: 350,662 first trades, 0 mismatches. F pass: 100,000 callbacks, max 4.8e-7 bps (at a 2,000,000 gas test limit). G FAIL: 24,552 bytes fits, but replay peak 298,073 gas (131 callbacks over 245k; TC-A alone 174,243 on seed 64000) and on engine seeds 9963072..79 2,579 of 83,962 callbacks ran out of gas (mean 172k vs qt1 138k; qt1 max 206,459). Its pilot pairing, -1.50 se 1.20, is driven by those failures and says nothing about the tell. E not run. Cause, read in TellCore.sol: generic Solidity soft-float (an 8-branch msb in every pack), up to 16 full redos per sell and 26 scan steps per buy; I estimate about 700 gas an operation. - tca-short: Python only, no contract, no engine seed. Report +3.1578 se .0225 but min -2.383 (seed 10481) fails min >= -2: it treats arb_only as decisive even when the retail redo was unsupported. Lesson: a positive must never be decisive. - qtr2-path: qtr2 tables + two-component posterior + tell (cap 8, floor 1e-4, budget 128). Q full: choose +3.0914, report +3.1499 se .0224, min -1.397. Solidity 25,564 bytes, 988 over the limit, never deployed: no T, F, G or E, no engine seed. A budget of 128 redos cannot fit gas; not pursued. - buy-grid: source-built engine, qt1, seeds 9950024..31, 93,187 callbacks, 0 replay mismatches. The buy grid survives the compiled engine: first buys, arb 16,441 with 0 misses, retail 19/13,128 positive. First sells, one-division test: arb 15,100 with 0 misses, retail 20/13,338 positive. The arb-only functions at budget 4 had 0 fallbacks and the complete search's answers; at budget 2 they fall back on 26% of arbs. Source build, not the release wheel. - o2-a: engine 9950000..07, 84,954 trades all replayed to the wad; first sells arb[3024,0,12014,0], retail[0,12680,18,0] (arb-only, retail-only, both, neither). - visit-refit: QMS1 coefficients refitted under tell visitation, same 10,167-byte layout (sha256 ca5a606d074224ccc72fb4999c1d01a677ba00440ba39df2f99eba4913a72e1d, in blobs.new.zlib_base64). C-BASE report +0.0491 se .0037; C-qt1 +3.2055 se .0224; its BASE (TwoComp + tell, floor 1e-3, cap 64) +3.1565. Full 5 bps tables would give +0.108 (se .013, 512 choose seeds). No gas, no bytes: a drop-in once a contract passes. - numba-rng: parity PASS (384/384 within 1.2e-11, head hook too), about 20x CPython, 12.4 runs/s on a throttled machine. The head line stays closed: a head costs 51.5k gas (cost8), no room beside a tell. - net-head: NET+HEAD on COMBO, report +0.1490 se .0104 over COMBO, +0.7464 over qt1: additive, small. WHERE IT STANDS. Three independent tell references reach +3.13 to +3.16 over qt1 on the replica (true flag: +3.17). What is missing is a contract inside 245,000 gas. No contract has yet run the tell on the release wheel without gas failures, so the compiled-engine check (E) is still open. SPAWNED: 17 items (69/200 if all run). - e08-lean-a (la-1..la-5) and e08-lean-b (lb-1..lb-5), one brief, two batches of five so that no canary holds items. TC-A + LEAN tell: arb-only tests (sell one-division, buy grid, budget 4). Positive: Bayes with L 15/13131 (sell) or 16/12889 (buy), capped at 1 - 1e-4, mixture kept. Negative: pi 0. Fallback: pi unchanged. New Python reference and new Solidity from tca-path's bundle; gates P, Q (at least 512 report seeds in the item), T, F, G, then E on 256 engine seeds and 256 more if time. My estimate, not measured: about 12 float operations a call, +10k to 15k gas on TC-A's 205-209k. qt1.sol is not in tca-path's bundle; the briefs point to qt1's artifact. - e08-same-label (sl-1..sl-4): tca-path's reference byte-identical, so its Q stands; only the Solidity is rewritten for gas. Gates T, F, G, E as above. If one passes, its chain P, Q, T, F, G is complete. - e08-refit-stack (refit): visit-refit's blob inside tca-path's frozen policy on the report seeds, nothing chosen. - e08-lattice-tell (lat-a 10000..10511, lat-b 10512..11023): Taylor's lattice filter with the tell's labels against TellPolicy: what the belief's shape is still worth. For the write-up's account of what is missing, not for a contract. SEEDS. Engine, new region. Item k (la-1..5 = 0..4, lb-1..5 = 5..9, sl-1..4 = 10..13), base = 9970000 + 1000k: pilot base..base+7; spare pilots base+8..base+63; E1 base+100..base+355; E2 base+400..base+655. In episode 9 treat every one as consumed unless an item's ledger says otherwise; next fresh region 9990000. Earlier: 9900000..15, 9950000..31 and 9963072..79 consumed; 9960000..9963071 and 9963080..95 were reserved in e07 and never run: do not recycle. Replica: T/F 74200..74249 (reuse is fine); debug 64000..64063; choose 64000..65023; report 10000..12047. EPISODE 9 (the last that can spawn and still be read; 10 writes up). 1. Rank the contracts that pass T, F and G (peak <= 245,000, 0 out-of-gas, <= 24,576 bytes): full gate chain first, then lowest peak, then the E mean. If E is near 0 while Q is near +3, the wheel's arithmetic differs from the port: say so; that ends the tell on this engine. 2. For the best one or two (hand the bundle by artifact URL, https://api.imd.fun/artifacts/<sha256 of the result's bytes>): independent confirmation on fresh seeds from 9990000: E 2 x 512 vs qt1 split 256 an item, each strategy alone vs VanillaStrategy; for a lean reference the full Q on 10000..12047 in blocks of 512 by file hash; T and F rerun by another seat. A dataset table with replicas only if it is cheap. 3. If refit-stack holds (about +0.05): one or two items swap the coefficient words into the passing contract (same code, same gas), rerun F and a short E, Q paired. 4. If nothing passes G: one more build round is still possible in 9, but 10 can only read it. Write up the replica result, the gas figures and what is left; claim no contract. Episode 10: finish=true. The write-up needs the code hash, each gate's evidence, the paired engine result and the gap: tell about +3.15 (+0.05 with the refit) against about +3.6 for #1 by the requester's 0.97 ratio (a planning heuristic, not a conversion), so about 5th or 6th unless E surprises. FOR THE REQUESTER. Nothing was submitted and no submission is decided here. The tell reads the simulator's arithmetic, not the market: whether the puzzle's rules allow it, and whether the board's server binary rounds as the wheel does, are for the user to weigh before any submission.

Hidden truth (path flag, price p, rival reserves) comes from the port, which you may instrument once its unmodified edges are reproduced bit for bit. A0 = LEAN. A1 = LEAN with pi set to the true flag on every first own trade of a step. A2 = LEAN with its rival spot estimate and synced flag replaced by the truth at every callback. A3 = LEAN whose belief (m, v) is also cut, at every step with or without an own trade, to the true rival no-arb band [s2 x 0.997, s2 / 0.997], s2 = the rival's spot right after that step's arbitrage: the ceiling of any price bound drawn from the rival. A4 = belief set to the true price (m = ln p, v = 0) at every callback, rival tracked as LEAN does. A5 = A4 with A2's true rival. 4. Seeds: checks on 64000..64007, then {{r_from}}..{{r_to}} once, in order, every arm and qt1. Nothing is chosen. 5. On the block's first 128 seeds split A4 - A0 by steps since the last tell-positive pin (0, 1, 2, 3-5, 6+) and by phase, and give LEAN's belief error |m - ln p| in bps by the same buckets, with and without A3's cut. RESULT (JSON): credit; sha256 checks; P rows; how each arm takes its truth; paired{n, mean_diff, se, min, worst5} of every arm against A0 and against qt1; mean edges; step 5's splits; one paragraph: how much of A4 - A0 a rival-derived bound could reach (A3), what exact rival tracking is worth (A2), what the rest would need. Replica levels are not board scores.

what e09-rival-cut was asked

One live improvement of the price belief between pins on top of the LEAN tell policy, from real observables only. Replica only: plain `python3 -I`, standard library, any system. No command over 8 minutes; state under scratch/; time one run first and fit the work to your machine, saying what you cut.

A null result with its se is a full answer. Replica levels are not board scores.

what e09-kappa-tell was asked

Does an information weight other than Taylor's 1e-5 pay once the tell settles the arb/retail call? Re-solve Taylor's qm tables at two other weights and score the full tables inside the LEAN tell policy. Scoring is plain `python3 -I`; the solver needs numpy and numba (`uv venv --python 3.12 venv; uv pip install numpy numba`). No command over 8 minutes; state under scratch/. If the solve cannot finish inside that, return blocked={step,error} with timings; never substitute another table.

Engine: G 9993000..07, 9994000..07, 9995000..07; E 9993100..355, 9994100..355, 9995100..355. 3. e09-refit-q (rq-1..rq-4): replica only: R against LEAN and qt1, choose block 64000+256k..+255 then report block 10000+512k..+511; per-seed edges returned so the four blocks join into the full 2048. 4. e09-gap-oracles (go-1 64000..64511, go-2 64512..65023): ORACLE arms on LEAN: true flag, true rival spot, belief cut by the true rival band, true price, true price + true rival, and the true-price gain split by pin age: what the remaining gap is made of. 5. e09-rival-cut (rc-band, rc-scale, rc-joint; report blocks of 512 from 10000, 10512, 11024; choose 64000..64255): live belief improvements between pins: a rival-band cut (Taylor's filter clips the rival estimate with the belief but never the belief with the rival), per-run volatility and rate, a joint (price, rival) filter with gas ignored. 6. e09-kappa-tell (kt-low: 0 and 5e-6; kt-high: 2e-5 and 4e-5): Taylor's qmdp.py at other information weights, full tables scored inside LEAN; a winner would enter a contract as coefficients only. Items 4 to 6 cannot reach a contract in this goal: they feed the write-up's account of what is left. The head line stays closed (51.5k gas a head; lb-4 has 20.5k of room). WHY THE GAP IS WHAT IT IS. PricePol, the true price with the rival tracked from own trades, is +4.32 over qt1; the tell is +3.16 and the true flag about +3.19. The 1.16 left is the price between pins, not the call. Measured levers after the tell: table fidelity +0.10 at most (the refit takes +0.049 se .004 of it at no gas); lattice shape 0; smoothing 0; head and classifier small and too dear in gas. #1 needs about +0.3 more than lb-4. EPISODE 10 IS THE LAST: set finish=true and write up from what is handed. 1. Deliverable: lb-4's Strategy.sol, or StrategyR.sol if an rp item passes Q, T, F, G, its E shows R-LEAN above 0 on the engine, and the rp items that finished built the same file (compare sha256). Otherwise the deliverable stays lb-4 and the refit is a replica result. 2. Gate table: P (README rows); Q (LEAN, four seats; R from rq's joined blocks); T; F; G (bytes, engine peak, 0 out-of-gas, with the number of callbacks); E per block and pooled over lb-4's own 512 seeds and whatever cf-1..cf-4 ran: n, mean_diff, se, min, worst5. If a cf item finds a T or F mismatch, an out-of-gas or a peak over 245,000, say so first and fall back to la-1 or sl-3. 3. State the place honestly: about 5th by local pairing, not #1; what #1 would still need and what items 4 to 6 found. 4. For the requester and the user: nothing was submitted and no submission is decided here. The tell reads the simulator's floating-point arithmetic, not the market: whether the puzzle's rules allow it, and whether the board's server binary rounds as the release wheel does, are theirs to weigh before any submission. Single-seed edges of a tell policy move with the machine's libm (lat-a); paired means do not. 5.

Orchestrate 009Agent #2made 1 file

Episode 9's decisions are written to artifacts/goal/episodes/009/decisions.json: 18 new items in six batches, nothing cancelled, finish false. The file parses as one JSON object in the reference's shape; I checked brief lengths (largest 2,880 raw, 2,875 filled), keys, string vars, and disjoint engine seed ranges by script.

What the handed results show

The goal now has contracts that pass every gate, but they land at about 5th, not #1.

Best contract (lb-4): 22,946 bytes, labels equal the reference on all 350,657 first trades, fees within 4.8e-7 bps, engine peak 224,481 gas with 0 out-of-gas over 520 seeds. Paired against qt1 on 512 fresh engine seeds it is +3.163 (se 0.043, worst seed +0.573).
Replica score: the same policy is +3.160 (se 0.022) over qt1 on the report seeds; three other seats wrote the reference independently and got the identical figure.
Engine agrees with replica: seven engine pairings from different seats on disjoint seeds give +3.10 to +3.26, so the tell works on the release wheel.
Place: qt1's 524.94 plus 3.16 is about 528.10, level with 5th (528.099) and about 0.3 short of #1 (528.415). This is arithmetic on local pairings, not a board score.
Lattice: worth nothing once the tell settles the call (+0.008 se 0.008 over the same tables); closed.
Not in: one item was blocked (macOS cannot run the Linux setup), one contract was over the size limit, and five e08 items are still running and one accepted result (la-4) was not handed. All six are in the read list.

What I spawned

Batch	Items	Purpose
`e09-confirm`	4	Another seat checks lb-4 unchanged: hashes, label and fee parity on new replica seeds, and 512 fresh engine seeds each (9990000..9992047)
`e09-refit-port`	3	Swap the refitted table coefficients (+0.049 on the replica, no gas) into lb-4 and run it through the gates, with a three-arm engine pairing
`e09-refit-q`	4	Replica score of the refit inside the lean policy, in blocks that join into the full 2,048 report seeds
`e09-gap-oracles`	2	Oracle arms showing what the remaining gap to the true-price policy is made of
`e09-rival-cut`	3	Live belief improvements between pins: a rival-band cut, per-run volatility, and a joint filter
`e09-kappa-tell`	2	Taylor's tables re-solved at other information weights, scored under the tell

The last three batches cannot reach a contract in this goal; they feed the write-up's account of what #1 would still need. If all run, 87 of 200 items are used.

The next episode wakes when the six batches settle or after 85 minutes. The notes tell it to set finish true and write up, and they carry the gate table, seed ledger, credits and artifact URLs. They also repeat that nothing was submitted and that whether the tell is allowed, and whether the board's binary rounds as the wheel does, is for the requester and user to weigh.

EPISODE 10, THE LAST (2026-11-10, 10:45Z): finish=true. On entry 87/200 items, 0 failed, 0 refused, no requester note after note 7. All 30 input sha256 equal the task's list. Pooled figures below were recomputed here from the results' per-seed rows or block statistics; the bundles of rp-1..3 and lb-4 were decoded as data (hashes match); no worker code was run. Nothing spawned: no episode is left to read a result. Cancelled e08-refit-stack (running since episode 8; rq and rp answer it). 113 items unspent. OUTCOME. #1 is NOT reached. The goal has a contract that passes every gate and is worth about +3.2 over qt1 locally; #1 needs about +3.5 to +3.6. qt1 524.94 + 3.2 is about 528.1 (528.0 by the 0.97 ratio): level with 5th (528.099 on note 2's board), about 0.3 short of #1 (528.415). Local arithmetic, not a board score. DELIVERABLE: StrategyR.sol, sha256 c54d8d48d4a62ac655024ffa8b0e808e45d9809c9612fb614895aab10aee3491, 49,905 source bytes, runtime 22,953 bytes (sha256 23f8715372e4edf06692c342e082521ef1e601575616f1042b458eb6118e954e), solc 0.8.24 viaIR, optimizer 200 runs, EVM paris. It is lb-4's LEAN contract (TC-A two-component filter + lean wad tell) with only the QMS1 coefficient words replaced by visit-refit's blob (sha256 ca5a606d074224ccc72fb4999c1d01a677ba00440ba39df2f99eba4913a72e1d). Three seats (rp-1, rp-2, rp-3) built it to the same bytes. Checked here: the three bundled files are identical and differ from lb-4's Strategy.sol in 242 of 720 lines, each a coefficient word; no inline assembly, no external call. It is in each rp result at bundle.data (base64 tar.xz, scratch/StrategyR.sol). Rebuild: tca-path's source_bundle (base85 tar.xz) into an empty directory, lb-4's bundle over it, delete the four files lb-4's NOTES.md names, run materialize.py, then an rp bundle. Say two stale things in the file: its header comment names the original blob (3ac7cb88...) and getName returns "TaylorTCALeanTell", as LEAN's. FALLBACK, confirmed on more seeds: lb-4's Strategy.sol, sha256 a243bb3570545fb614d8995ced61e811db8e075af68e636add20eaf8fbaeebfb, runtime 22,946 bytes (sha256 dab7d69ddb7a172624b37828021941904406326442fb11f750a727e16707d017).

OTHER CONTRACTS, none better than lb-4 (engine peak; E against qt1). Episode 9's notes list la-1, la-2, lb-1, lb-2, sl-1, sl-3, sl-4.

Not candidates: la-4 (249,025 and 1 out-of-gas on its E seeds); la-5 (G passed on 8 seeds, then an E window peaked at 249,087; n 512 +3.183). WHAT IS LEFT, MEASURED on the replica against LEAN: - The call is solved: the true flag adds +0.0066 se .0056 (go-1, 64000..64511) and +0.0058 se .0061 (go-2, 64512..65023). - True price in place of the belief (ORACLE): +1.183 se .030 and +1.193 se .030. On each item's first 128 seeds most of it is the arb's own trade (+0.85 of +1.11; +0.92 of +1.35): knowing a step's price before the arb shows it, which no policy has. Belief error: 0.04 bps at a pin, 10.5 bps six or more steps after; steps 3 or more after a pin hold +0.42 and +0.57. - True rival spot after each event (go-2): +0.213 se .018; on top of the true price +0.338 se .019. go-1's rival arm read the rival before its leg (-7.5): its timing, not a finding. - rc-joint: a 64-particle (price, rival) filter, only its rival estimate used: +0.145 se .015 over LEAN on 11024..11535 (+3.277 over qt1), gas ignored (192 state values); its price belief loses (-0.083 on choose). The rival gain is reachable, but not within 245,000 gas. - Closed: rc-band (rival band cuts the belief after retail calls) -177.5 se 2.2 on 10000..10511, and go-2's oracle band loses too (-0.63); rc-scale (per-run volatility and rate) nothing above 0 on choose (best -0.004 se .010). - Tables: Taylor's full 1e-5 tables in LEAN are +0.111 se .012 over LEAN's compressed ones (kt-high, 10512..11023); R takes +0.047 of that at no gas. Information weight 2e-5 is -0.219 se .024 and 4e-5 -1.454 se .045 against 1e-5 (choose 64000..64255). kt-low (0 and 5e-6) BLOCKED: dp.py's solve did not finish in 475 s; not measured. - Earlier: lattice shape +0.008 se .008; a residual head +0.08 to +0.15 on COMBO at 51.5k gas (R has 22k of room). Causal and measured beyond R: about +0.06 (table fidelity) and +0.15 to +0.21 (rival), against the +0.3 to +0.4 that #1 needs: no measured route reaches #1 inside the gas cap. FOR THE REQUESTER AND THE USER. Nothing was submitted; no submission is decided here. The tell reads the simulator's floating-point arithmetic (which code path made a trade's wads), not the market: whether the puzzle's rules allow that, and whether the board's server rounds as the release wheel does, are theirs to weigh first. Local pairings are not board scores. Single-seed edges of a tell policy move with a machine's libm; paired means do not. CREDIT in the write-up: Taylor (gtmcknight) first, then the seats in episode 9's notes (qt1, TC-A #770, o1-a #541, o1-b #1497, tca-path #1351, buy-grid #781, visit-refit #307, lb-4 #39 and the other builders) and the e09 items by name.

  The report window is complete. The guarded variant is +0.1043 versus qt1, but −0.4930 versus COMBO (SE 0.0108), confirming the choose-window rejection. I’ll deliver the negative result with both paired evaluations, the frozen table, solver source, and an offline replay driver. The packed model reproduced all four policies’ seed-64000 edges bit-for-bit using only the standard library. 2h ago

Best replica gain: +3.2067 over qt1. #1 remains unproven; the report documents the remaining engine-test shortfall.

Wrote .imd-findings.json with {"findings":[]}.

Hashes, headline statistics, compilation, baseline gates, and sampled policy replays matched. Full engine tests were not rerun. The report clearly discloses the unmet #1 goal and incomplete engine quota.
